说明：  根据语音信号的特点给出有关滤波器的性能指标：1）低通滤波器性能指标，fp=1000Hz，fc=1200 Hz， As=100dB，Ap=1dB；2）高通滤波器性能指标，fc=2800 Hz，fp=3000 Hz As=100dB，Ap=1dB；3）带通滤波器性能指标，fp1=1200 Hz，fp2=3000 Hz，fc1=1000 Hz，fc2=3200 Hz，As=100dB，Ap=1dB。用IIR对其分析，最后，利用MATLAB中的函数freqz画出各滤波器的频率响应。(This article according to the IIR filter and the FIR filter characteristic, uses the bilinearity method of transformation under the MATLAB bad boundary to design IIR and to design the FIR numeral filter separately with the window box number, and carries on the analysis to the gathering pronunciation signal, and finally gives IIR and FIR to the pronunciation filter effect.)

说明：  利用AR模型实现功率谱估计的方法，包括直接求解，L-D递推，自相关法和Burg算法。(AR model power spectrum estimation methods, including direct solving LD recursive autocorrelation method and Burg algorithm.)

固定个数，不动点ICA算法的语音信号盲源分离(A fixed number of fixed point ICA algorithm speech signal blind source separation)

《小波分析理论与Matlab7实现例程》一书里面各章节的源码，可以直接使用，对于学习很省时间。("wavelet analysis theory and Matlab7 achieve routines," a book which all sections of the source code, can be directly used for the study is time.)

中频数字正交采样，并进行滤波，得出基带信号(IF quadrature sampling and filtering)

画出地貌地形图，熟悉各个matlab语句的掌握与运用，掌握运用插值函数的调用格式，对各种调用函数的格式语句要能够熟练的应用(Draw terrain map, master and use the MATLAB statement, master the use of interpolation function call forms, application format statement of a function call to be able to )

用于计算汉字笔画的程序,可对多个汉字同时计算(The procedures used to calculate the Chinese character strokes)

频域内低通滤波实现图像平滑，程序原代码来自书籍，《计算机图像处理与识别技术》，作者王耀南等(frequency low pass filter)

整数规划，分支定界法，实现1000变量（变量个数可自行设定），只需改变原始数据，就能运行！是比较好的分支分支定界法程序设计(Integer programming, branch and bound method to achieve the 1000 variables (number of variables can be set on their own), simply by changing the original data, you can run! Branch is a better programming branch and bound method )
